ZeroMQ(一)——error while loading shared libraries: libzmq.so.5: cannot open shared object解决方案

作者:互联网

问题

下面是一段调用ZeroMQ接口的程序:

#include <zmq.hpp>
#include <string>
#include <iostream>
#include <unistd.h>
 
int main () {
    // Prepare our context and socket
    zmq::context_t context (1);
    zmq::socket_t socket (context, ZMQ_REP);
    socket.bind ("tcp://*:5555");
 
    while (true) {
        zmq::message_t request;
 
        // Wait for next request from client
        socket.recv (&request);
        std::cout << "Received Hello" << std::endl;
 
        // Do some 'work'
        sleep (1);
 
        // Send reply back to client
        zmq::message_t reply (5);
        memcpy ((void *) reply.data (), "World", 5);
        socket.send (reply);
    }
    return 0;
}

编译运行时报错

[root@192 day20211007]# g++ server.cpp -o server -lzmq
[root@192 day20211007]# ls
server  server.cpp
[root@192 day20211007]# ./server
./server: error while loading shared libraries: libzmq.so.5: cannot open shared object file: No such file or directory

解决方案

(1)打开/etc/ld.so.conf文件

[root@192 day20211007]# vim /etc/ld.so.conf

(2) 在文件中添加libzmq.so.5所在的路径,我的路径为/usr/local/lib

include ld.so.conf.d/*.conf

/usr/local/lib/

(3)修改完成保存,执行ldconfig命令刷新动态库

root@192 day20211007]# ldconfig
